Use Blocking > Pre-Mesh Params > Refinement to refine or coarsen the mesh. You can apply the refinement/coarsening in all three major directions simultaneously or in just one major direction.
- Refinement
You can use refinement for solvers that accept non-conformal node matching at the block boundaries. The refinement capability minimizes the model size while achieving proper mesh definition in critical areas of high gradients. To refine the mesh, enter a scale factor greater than 1.
- Coarsening
In areas of the model where the flow characteristics are such that a coarser mesh definition is adequate, coarsening of the mesh may be appropriate to contain model size. To coarsen the mesh, enter a scale factor less than 1.
